Mobile Health v. Citizen Watch: Joint Dismissal With Prejudice After 238 Days
Mobile Health Innovative Solutions, LLC filed a patent infringement action in the Western District of Texas against Citizen Watch Co., Ltd., asserting US11468984B2 against the CZ Smart Sport and CZ Smart Casual Touchscreen smartwatches. The parties jointly moved to dismiss all claims with prejudice after 238 days, with each side bearing its own costs and attorneys’ fees.
Smartwatch patent dispute ends in joint with-prejudice dismissal
Mobile Health Innovative Solutions, LLC initiated this infringement action on April 7, 2025 in the Western District of Texas, asserting US11468984B2 against Citizen Watch Co., Ltd. The patent at issue relates to mobile health monitoring technology, and the accused products were Citizen’s CZ Smart Sport Touchscreen and CZ Smart Casual Touchscreen — consumer smartwatches marketed with health and activity tracking capabilities.
The case closed on December 1, 2025 via a joint motion filed by Mobile Health and Citizen Watch Company of America, Inc. The court granted the motion and dismissed all claims of infringement that the plaintiff raised or could have raised, with prejudice. Critically, each party was ordered to bear its own costs, expenses, and attorneys’ fees, suggesting the parties negotiated a clean exit without any admitted liability or monetary transfer on the public record.
At 238 days, the case resolved before reaching claim construction or trial — consistent with a negotiated resolution reached during the early litigation phase. The with-prejudice designation and the mutual cost-bearing arrangement are notable: they foreclose refiling while leaving the underlying commercial terms, if any, undisclosed. What drove the joint dismissal — whether a license, a covenant not to sue, or a strategic withdrawal — remains unknown from the public record.

Joint dismissal with prejudice: what the order means for both parties
Dismissal with prejudice bars any refiling on these claims
A dismissal with prejudice is a final adjudication on the merits for res judicata purposes. Under Federal Rule of Civil Procedure 41, the court’s order extinguishes all claims Mobile Health raised or could have raised against Citizen Watch relating to US11468984B2 in this action. Mobile Health cannot refile the same infringement claims against Citizen Watch on the same patent in any federal court.
Permanent bar on refilingPlaintiff surrenders right to pursue Citizen Watch on this patent
By agreeing to a with-prejudice dismissal, Mobile Health Innovative Solutions permanently forecloses enforcement of US11468984B2 against Citizen Watch for the accused CZ Smart products. The patent itself remains valid and enforceable against third parties, but Citizen Watch gains a complete defense should Mobile Health or any successor attempt to relitigate. This outcome is consistent with either a confidential license or a calculated strategic withdrawal.
Patent survives; Citizen Watch protectedCitizen Watch secures a permanent release from this infringement action
Citizen Watch and its U.S. subsidiary obtain a court-ordered, permanent dismissal covering all claims that were or could have been raised. Defended by Jones Day and Potter Minton PC, the company exits without any public admission of liability. The mutual cost-bearing arrangement means no fee-shifting award was granted — Citizen Watch absorbs its own defense costs, which is typical where parties negotiate exit terms rather than litigate to judgment.
No liability admitted; full release securedCZ Smart product line cleared — but US11468984B2 remains active against others
The dismissal clears Citizen Watch’s CZ Smart Sport and CZ Smart Casual Touchscreen lines from this specific litigation risk. However, US11468984B2 remains an active, enforceable patent that Mobile Health could assert against other smartwatch and wearable health-monitoring manufacturers. Competitors in the consumer wearables space should note that the patent’s claims were never adjudicated on the merits, leaving claim scope legally unresolved.

Official order — verbatim text
The court’s order tracks the joint motion language precisely, dismissing ‘all claims of infringement that Plaintiff raised or could have raised’ — the broadest possible with-prejudice scope, extinguishing not just pleaded claims but any infringement theory Mobile Health might have advanced. The inclusion of Citizen Watch Company of America, Inc. (the U.S. subsidiary) as a named party to the motion, alongside the Japanese parent, suggests the release was structured to cover both entities. The own-costs provision is commercially neutral and typical of negotiated exits at this litigation stage.
US11468984B2 — mobile health monitoring for smartwatch platforms
US11468984B2 was filed under application number US16/850984 and issued as a utility patent covering mobile health innovative monitoring technology implemented on touchscreen wearable devices. The patent’s asserted claims were directed at health data functionality of the type commercially deployed in consumer smartwatch platforms — covering the acquisition, processing, or display of health metrics on a touchscreen wearable interface. The patent was asserted against Citizen’s CZ Smart Sport and CZ Smart Casual Touchscreen product lines.
The strategic significance of US11468984B2 lies in its breadth relative to the growing consumer wearables market. Citizen Watch is not the only manufacturer deploying health-monitoring smartwatch technology, and because no court has construed the claims or ruled on validity, the patent retains full enforcement potential against other defendants. Any competitor in the touchscreen smartwatch segment — particularly those offering health, fitness, or biometric monitoring features — faces non-zero exposure if Mobile Health pursues a broader licensing campaign.
Should your product team run an FTO against US11468984B2?
Any R&D or product team commercialising a touchscreen smartwatch, fitness wearable, or connected health monitoring device in the US market should evaluate exposure to US11468984B2. The claims were never adjudicated on the merits in this case, meaning the patent carries no court-imposed limitation on scope. Products featuring real-time health data monitoring, step or activity tracking, or biometric display on a touchscreen wearable interface are the most commercially proximate risk categories.
PatSnap Eureka’s FTO Search Agent can map US11468984B2’s independent claims against your product specification, identify prior art that could support an IPR or ex parte reexamination strategy, and surface any continuation or divisional applications that may extend the patent family’s coverage. Given that this case closed without claim construction, a proactive FTO and landscape analysis is the most defensible posture for wearable health tech product teams entering or expanding in the US market.

Portfolio viewWhat this case signals for the wearable health tech IP landscape
A with-prejudice joint dismissal in W.D. Texas without fee-shifting is a pattern consistent with confidential licensing or strategic portfolio management.
With-prejudice joint dismissals often signal undisclosed licensing activity
When both parties jointly move to dismiss with prejudice and agree to bear their own costs, the most commercially plausible explanation is a confidential license or settlement with non-disclosure terms. No admission of infringement is made, and the patent owner preserves the right to assert against other defendants. Wearable tech competitors should treat this as a signal that US11468984B2 may be actively licensed.
US11468984B2 claim scope was never tested — third-party risk remains open
Because the case was dismissed before claim construction, no court has ruled on the scope or validity of US11468984B2. Other smartwatch and health wearable manufacturers cannot rely on this dismissal as a signal of patent weakness. An FTO analysis against this patent is advisable for any company commercialising mobile health monitoring or touchscreen smartwatch technology in the US market.
W.D. Texas venue strategy: what Mobile Health’s filing choice reveals
Filing in the Western District of Texas — specifically the Waco/Midland divisions — remains a preferred venue for NPE-style plaintiffs despite post-TC Heartland shifts. The rapid resolution here suggests Citizen Watch may have prioritized early exit over contesting venue, a calculus other wearable defendants should model before assuming transfer motions are cost-effective in sub-year cases.
Portfolio risk: Mobile Health’s enforcement posture warrants ongoing monitoring
A plaintiff that files, obtains a with-prejudice dismissal with own-costs terms, and moves on without public fee exposure may be systematically licensing across the wearables sector. IP teams at smartwatch, fitness tracker, and connected health device companies should monitor Mobile Health Innovative Solutions’ filing activity and US11468984B2 continuation applications for forward citation risk.
Mobile v Citizen — key questions answered
The dismissal with prejudice means Mobile Health Innovative Solutions permanently lost the right to sue Citizen Watch on US11468984B2 for the conduct alleged in this action. The court’s order covers all claims raised or that could have been raised. Mobile Health cannot refile the same infringement claims against Citizen Watch in any US federal court.
The public record shows a joint motion for dismissal with prejudice and a mutual own-costs provision — a pattern consistent with an undisclosed settlement or license. However, no settlement agreement, license terms, or payment details appear in the public docket. The commercial terms, if any, are not confirmed by the court’s order.
Yes. The dismissal only bars Mobile Health from suing Citizen Watch again on this patent. US11468984B2 remains an active, issued US patent with full enforceability against other parties. No court has ruled on the validity or claim scope of the patent, which means third-party manufacturers of smartwatch and health wearable products remain potentially exposed.
The complaint identified the CZ Smart Sport Touchscreen and the CZ Smart Casual Touchscreen as the accused products. Both are consumer smartwatches in Citizen’s CZ Smart product line featuring health and activity monitoring capabilities on a touchscreen interface.
Mobile Health was represented by M. Scott Fuller, Randall T. Garteiser, and Rene A. Vazquez of Garteiser Honea PLLC and DNL Zito. Citizen Watch was defended by Evan M. McLean, Gurneet Singh, Michael E. Jones, Nicole Smith, and Shaun William Hassett of Jones Day and Potter Minton PC.
